Abstract

Det er beskrevet en sonde (1) til måling av oksygeninnholdet i biologisk vev. Sonden har minst en optisk fiber (2) som proksimalt kan kobles optisk til en lyskilde på den ene siden og til en lyssensor på den andre siden. På en distal endeflate av fiberen (2) er det anordnet, og til denne optisk tilkoblet, et oksygenfølsomt fargestoff (5). Et distalt fiberavsnitt (6) innbefattende den distale endeflaten er, sammen med fargestoffet (5) omsluttet av en oksygengjennomtrengelig og væskeugjennomtrengelig membran (7), som definerer, i det innelukkede området, et gassrom (8) som omgir den distale endeflaten med fargestoffet (5). Sonden (1) er bestanddel av et kateter (14) som i tillegg oppviser en temperatursensor (30) og fortrinnsvis en trykksensor (28). Det oppstår derved en sonde hvori følsomheten av fiberen mot ytre påvirkning ved målestedet er redusert og hvorved tolkningsmulighetene av måleresultatene er forbedret.A probe (1) for measuring the oxygen content of biological tissue is disclosed. The probe has at least one optical fiber (2) which can be optically coupled optically to a light source on one side and to a light sensor on the other side. On an distal end surface of the fiber (2) there is provided, and to this optically connected, an oxygen sensitive dye (5). A distal fiber portion (6) comprising the distal end surface is, together with the dye (5), enclosed by an oxygen-permeable and liquid-permeable membrane (7) defining, in the enclosed area, a gas chamber (8) surrounding the distal end surface with the dye ( 5). The probe (1) is a component of a catheter (14) which additionally has a temperature sensor (30) and preferably a pressure sensor (28). There is thus a probe in which the sensitivity of the fiber to external influence at the measurement site is reduced and whereby the interpretation possibilities of the measurement results are improved.
